Patented Feb. 19, 1918.

Applioationvled July 11, ,1916, Serial No. 198,087.

Be it known that .I. 'Timor V. BUCK- WALTER, a. citizen lof vthe United' States, residing at Altoona, in the count-y of Blairand State of Pennsylvania, have invented an improved Radiator, of which the lfollowing 1s a s ecication.,

This invention isan improved radiater'er vcooling engines, especiallyT of the internal y :The primary object of my invention is to Q provide a rrmore ecient cooling system,

which will Joperajte eiciently at all times, whether the car is running forward, backward or standing still.

A further object of my invention is to prevent a draft, through Ithe center of the coolins apparatus., that would interfere with the dean-sgi circulation of the air in contact with thefdirfaces to, be cooled.

'The nature and characteristic function of my invention, willfully ap eal; from the following description and t e accompany' ing drawings in illustration thereof. l

In the drawings, Figure 1 is a part sectional elevation of an embodiment of my invention; and Fig. 2 is a sectional -view taken on the line2-2 of Fi 1.' v y The invention, in tie form lthereof 'illusjtrated in thedrawinga comprises the su f' ports V1 (Which'may'be longitudinal'sills o 'a car) having. the'radiator 2 mounted thereong., the radiator com rising a cooling iiuid circulating system having a` to header 3, a bottom header 4, and sets o tubes.5 with.'

their respective ends connected by the: headers 3' and 4.

Plates 2', containing apertures 2 ,connect the headers 3 and 4 on opposite sides lof the tubes 5, and form therewith a'partially inclosed space for the tubes, the space having free central openings -in the a ertures 2" between the sets of tubes an the free end openings 2 at opposite sides thereof.

Open bearings or spiders 6 and 7,1ixed to the plates 2', over `the apertures 2 on opthe circulating system is actively cooled by an.

posits sides of the structure, carry the shaft 8. A hub or hollow shaft 9 is journaled 0n the shaft 8 and-has thereon a solid diaphragm or web 10 providedwith conoidal sections' 10' and 10 fixed to the hub, varies .11 ,heilig fixed on oppositesides'of the pev of the web and supporting rings 12 connecting the outer ends of the vanes. The vane wheel or `vfan thus' rovided, is revol'ved b. a sprocket wheel 1 which is fixed A to the hu 9 and driven in a usual manner.

Baos or chokers 15 are ixod to the respecti've 'headers 3 and 4, between the plates 2 and the sets of vtubes 5, so' that the free space around the vane wheel shall be restrict ed andthe eiciency of 'the blower increased, the effect being to obtain a more active circulation of air 1n contact with the tubes.

the revolution .of the vane wheel draws air through the central' apertures 2 and forces vit outwardly in op osite directions, between the plates 2 and t e headers 3 and 4, through the spaces containing the tubes 5,

forced draft at all times,l Whether ithe 'apparatus is stationary orl moving in 'either dlrection. As the web 10 of the sans wheel is dis- -posed between the `rports B'f"transversely' to the'direction of movement, which is vin line with the axis of the wheel, the direct passage.' of air between the ports is prevented and its active-circulation 1n contact with the tubes is compelled' without regard to the'direction of movement of the apparatus, the pressure .im

of the air to the direction of move-j ment facilitating the" coolin action by-producing a draft throughdhe orward aperture'- snd'outwardly over the tubes due to'.thel-d ,ldtlon 0f thvfn Wlb. "f el Having described my .inventiflffl claim:

1. In .a radiator, the oombinili .With a "structure comprising cooling u 'd 1r'a'irculatling means and having apertures orthe pasair for cooling said means, olii jourtact with said means and having a )dlaphragm adapted for preventing the `direct passage of air between said apertures.

2. In 'a radiator, the combination with cooling Huidx circulating means comprising la pluralityof setsof tubes, of air circulating means comprising ajournaled fanhaving vanes adapted for forcing air outwardly be- .tween said tubes and a dlaphragm on opposite sides-of which the venes aforesaid are.v disposed.

'ro I Meist.. 10 naledr an adapted .for circulating air mysan 3. In a radiator, the combination with co01- ing Huid circulating means comprising headers and sets of tubes having their ends connected by said headers, of a Journaled fan between said sets of tubes and said headers, said fan having a diaphragm, and means providing air ports on opposite sides of said an, said ports being separated and the passage of air between vthem being prevented by said diaphragm.

' In a radiator, the combination With cool ing fluid circulating means comprising headers and sets of tubeshaving their ends connected by said headers, of plates connected with said headers and havin oppositely 15 disposed apertures, a journaied Wheel having a web wheel and for facihtating the active eircula- 20 tion of air by said Wheel in contact with said tubes.

In testimony whereof Irhave hereunto set my name this 29th day of June, 1916.
